This study aimed to compare patients' experience of pain during ultrasound (US)-guided peripheral venipuncture versus conventional peripheral venipuncture. This randomized clinical trial was conducted at a public university hospital in 2021. Adult patients with indication for intravenous therapy compatible with peripheral intravenous catheters (PIVCs) were included: intervention group (IG), US peripheral venipuncture executed by specialist nurses; control group (CG), conventional peripheral venipuncture executed by clinical practice nurses. The primary outcome was patient experience of pain during the procedure and patient experience related to the PIVC placement method. Sixty-four patients were included, 32 for each group. The pain experienced was none-to-mild in the IG for 25 patients (78.1%) and moderate-to-severe in the CG for 21 patients (65.7%; P < .001). The overall pain rating was 2 (1-3) in the IG and 4 (3-6) in the CG (P < .001). The recommendation of the procedure in IG (net promoter score [NPS] + 90.6%) versus CG (NPS + 18.8%) was considered excellent and good, respectively (P < .001). Patients had less pain and significantly recommended the US-guided procedure. Patient experience with US-guided PIVC, performed by a specialist nurse, was superior to that of conventional peripheral venipuncture.
